Low-temperature heating body Compact Softline is made of fine cold-rolled sheet steel according to EN442-1 quality, with side panels and a top grille, forming a compact unit with a vertical water channel spacing of 33.3 mm. The convector sheet is welded to the internal channels. Before painting, all radiators go through a multiple-stage cleaning process, including phosphating with iron phosphate and a demineralised rinse. A primer coat is then applied, followed by a powder coat finish in Stelrad white 9016. Each radiator is packed in cardboard with sturdy corner protectors and a protective film. All bodies have mounting brackets on the back. Quality is certified according to EN ISO 9001. Heat output is verified according to EN 442. The design complies with the BAGUV safety directives.

Frequently Asked Questions

• What is the output of this specific radiator (400 x 1100 mm, type 22VK)? This size and type version has a declared heat output of 1370 W (according to EN 442, at standard temperature drop) - when choosing the correct radiator size, base your choice on the calculated heat loss of the given room.
• What does the type designation 22VK mean? The number before "K" (e.g. 11, 20, 21, 22, 33) indicates the radiator's construction type - the number of radiator panels/plates and convector sheets in its make-up; a higher number means more layers and therefore a higher output at the same external dimensions. The "V" designation in the type means bottom connection (valve-compact) - the connections are located on the bottom edge of the radiator, which is especially suitable for underfloor pipe routing without visible risers.
• What is the maximum operating pressure and temperature? The radiator is designed for an operating pressure of up to 1.0 MPa and a heating water temperature of up to 110 °C, with a test pressure of 1.3 MPa - typical home heating systems operate well below these values.
• What is the warranty on the radiator? The manufacturer provides a 10-year warranty on tightness and heat output from the date of manufacture, provided professional installation, proper maintenance and operation are observed - the warranty does not cover mechanical damage caused during transport, handling or improper installation.
• Must installation be carried out by a professional? Yes, connecting the radiator to the heating system (single-pipe or two-pipe, with forced circulation) should be carried out by a heating engineer/installer, who will also ensure correct venting and balancing of the circuit.
